"qATTACHMENT F OR' FILLING-CANS.

SPECIFICATION forming part of Letters Patent No; 381,236, dated April 17 I888...

Application meg January 30, 188 8. s riolno. 262,336. (Moaoi) To all whom it may concerm Be it known that 1, JOHN H. J.- HAINES, a citizen of the United States, and a resident of Flushing, in the'county of Queens and State of New York, have invented a certain new and usefuLAutomatic Check Attachment for Filling-Oans,of which the following is a speci,

A fication.

- The object of my invention is to provide a simple, effective, and cheap device adapted for attachment to filling cans or vessels of any description, and designed to automatically stop the fiowof liquid from the can or vessel into the vessel or receptacle into which the liquid is being poured when the level of the liquid in the latter reaches a predetermined point, thus avoiding the danger of overflowing the latter.

My invention is designed principally for application to filling-cans intended to hold-illuminating-oils and used in filling lamps,th0ugh it can be employed in connection with any sort of a vessel or can intended for use in decanting the liquid into another vessel or receptacle and provided with a suitable nozzle or spout.

In the accompanying drawings, Figure 1 shows in side elevation an ordinary fillingcan with my improved attachment applied thereto. Fig. 2 shows in vertical section the mouth of the can, the cap, and the portion of the tube connected therewith. Fig. 3 shows in side elevation the check attachment separated from the can and having its elastic cap made in one piece with the flexible tube.

A indicates the .body of the filling-can, and D the nozzlethereof, from which the liquid O indicatesa flexible tube, of rubber or other suitable material, havinga tip, F, preferably made of some rigid substance, and provided with a means whereby it maybe attached to the nozzle D, as shown inoFig. 1. A convenient device for this purpose consists of a spring- I clip, G, Fig. 2, adapted to enter the nozzle D,

but not to interfere with the flow of liquid from the latter. g

The tip F may be made-of any'suitable material best adapted to resist. the action of the liquid with which the can is employed. When the checkis to be used with a coal-oilfillingcan, I prefer to make the 'tipof brass. At its terial-such as rubber-and may be formed "in onepiece with,or attached to or connectedwith, the flexible tube 0, as desired. The tube and cap are illustrated as madein one piece in Fig. 2. 'When made of rubber, it maybe sprung. over the mouth of the can A, so'as to same general nature it has opposite endthe tube .0 is providedwith a may be conveniently made of some elastic ma:

form an effectual seal against the entranceof air excepting through the. tube O. When made of rubber, it may also be applied readily to cans having mouths of various sizes. I may use any other form of cap adapted to embrace the mouth of the can on its outside in contradistinction to a plug; but I prefer to use an elastic cap, as indicated;

The tip F may be adjusted on the nozzle 'D,

in any desired position, either with its end flush with th'eend of the nozzle or beyond the same. It is preferable, however,

to arrange it in the manner shown.

. The flexible tube (3 adapts the check for attachment to cans of different sizes, as will be the manner indicated and liquid isdecanted from the can A into a vessel-such, for inprojecting I readily understood. When it is applied in stance, as a lamp-the liquid will continue to flow from the can aslongas the air is permitted to freely enter the space above the body of the liquid in the can. Air-will thus enter through the tube 0 and the mouthof the can so long as the tip F of the tube is exposed to the air but the moment the level of the liquid:-

in the vessel into which rho liquid isbeing poured rises so as to close the mouth of the tube 0 the flow of. liquid from the canwillfl cease,owing to a well-known principle of hy:

to insert-the nozzle'D into the vessel below the, top of the same. It is likewise obvious that drostatics'f By this means the overflowof the vessel may be entirely avoidedby taking care;

-the,vesselsuch as alampmay be filled to I any desired level by inserting the nozzle and tip F to the desired level.

I do not limit myself to the form of cap B shown, but prefer to employ the elastic cap described. A

2. As a new article of manufacture, a safety attachment for filling-cans consisting of a flexible tube having at one end a tip provided with means for attachment directly to the side of 20 v the spout or nozzle and parallel therewith, and having at its opposite end an elastic cap adapted to be sprung over the mouth of the can itself.

Signed at New York, in the county of New 25 York and State of New York, this 26th day of January, A. D. 1888.
